B-63324EN/03 PROGRAMMING 9.SPINDLE SPEED FUNCTION (S FUNCTION)
- 235 -
NOTE
11 The spindle positioning function is enabled only when
the number of position coder pulses is 4096, and the
gear ratio between the spindle and position coder is
as follows:
1 :2
n
n : Integer greater than 0
12 For a spindle positioning axis, CMR = 1 and DMR = 4
are used at all times.
13 For a spindle positioning axis, set the following
parameters as axis attributes:
1) The increment system is IS-B (0.001 deg)
Bit 0 (ISA) of parameter No. 1012 = 0
Bit 1 (ISC) of parameter No. 1012 = 0
Bit 2 (ISD) of parameter No. 1012 = 0
Bit 3 (ISE) of parameter No. 1012 = 0
2) The grid method is used as the reference position
return method.
Bit 1 (ZMG) of parameter No. 1005 = 0
3) In automatic reference position return (G28), the
tool returns to the reference position by rapid
traverse.
Bit 2 (ALZ) of parameter No. 1005 = 0
4) In manual reference position return, the
workpiece coordinate system is always preset.
Bit 3 (PLZ) of parameter No. 1005 = 1
5) Axis (rotation axis) for which inch/metric switching
is not required
Bit 0 (ROT) of parameter No. 1006 = 1
6) The machine coordinate system for stroke
checking and automatic reference position return
is of the rotation axis type.
Bit 1 (ROS) of parameter No. 1006 = 1
7) The machine coordinate system for stored pitch
error compensation is of the rotation axis type.
Bit 2 (ROP) of parameter No. 1006 = 1
8) Radius specification is used for specifying the
amount of travel on each axis.
Bit 3 (DIA) of parameter No. 1006 = 0
9) Command multiplication ratio = 1
Parameter No. 1820 = 2
10) The machine position is indicated in degrees.
Bit 1 (MCN) of parameter No. 2203 = 1
11) The amount of movement per rotation axis
revolution is 360 degrees.
Parameter No. 1260 = 360000
